Description

 Method for operating an electric motor driven food processor

The invention relates to a method for operating an electric motor driven food processor for preparing a preparation material based on a recipe, wherein the preparation is prepared in a vessel of the food processor by one or more successive preparation steps, in particular stirring and / or heating and / or crushing, wherein a current state parameter of the preparation good and / or a current operating parameters of the food processor is determined.

Electric motor driven kitchen machines in the sense of the invention are all semi-automatic or fully automatic operated kitchen machines, such as, for example, cooking mix appliances, with the aid of which a user can advantageously carry out several preparation steps of a recipe. These food processors usually have a vessel, which is associated with a heating device and an agitator, so that a cooking product contained in the vessel can be heated and / or stirred. In addition, it can also be provided to comminute the preparation material, knead or the like.

In the prior art, it is also known to determine a current state parameter of the preparation good or a current operating parameters of the food processor. Such a state parameter may be, for example, a temperature or a weight of the preparation material. In this case, the kitchen machine has corresponding sensors, for example a temperature sensor and / or a weighing device. A current operating parameter of the food processor may, for example, be a current temperature of the heating device and / or a current rotational speed of the agitator. With the aid of the determined state parameters and / or operating parameters, a user of the kitchen appliance can Machine or a control device of the food processor decide whether the actual state of the preparation material corresponds to the required state for an optimal result. If necessary, a correction can be made in case of deviations.

Although this approach has been well established in the art, it is desirable to further enhance the convenience of the user of the food processor in preparing a preparation. In particular, it is desired to support each user individually.

To further develop the method for operating an electric motor-driven food processor is therefore proposed that the food processor transmits information about the recipe currently used for preparation and the determined state parameters and / or operating parameters to a central data memory of a data communication network, the state parameter and / or the operating parameter is compared with reference parameters for this recipe, and wherein in the case of a deviation of the state parameter and / or operating parameter from the reference parameters, a correction proposal is transmitted from the central data memory and / or from members of the data communication network.

According to the invention, the food processor is a member of a data communications network. The data communication network has a central data store and other members. The data communication network can, for example, be a so-called "cloud" in which data, in particular data of the members, are stored in a locally remote central data memory However, the data communication network is also a private data telecommunications network, for example an internal or internal intranet. For data communication, the members, ie also the food processor, have a data communication module, for example a radio module. According to the invention, the state parameters and / or operating parameters of the current preparation are transmitted to the central data memory and compared there with reference parameters in relation to the respective preparation progress of the recipe. The state parameters of the preparation material may be, for example, a temperature, a weight, a density, a color and / or a viscosity. These state parameters are determined using sensors of the food processor or calculated from other known state parameters. For example. a temperature of the material to be prepared is determined by means of a temperature sensor arranged inside the vessel of the food processor or a weight of the material to be prepared is determined by means of a weighing device. Centrally stored reference parameters are then used for a comparison of these state parameters, which correspond to the respective same preparation progress of the recipe. If the comparison shows that the current temperature and / or the current weight deviates from the reference parameter, a correction proposal is made by the central data memory and / or by members of the data communication network. This correction proposal is suitable for correcting the preparation in such a way that the preparation material corresponds to the result expected according to the recipe or at least comes very close to it. It is possible that the creation of a correction proposal is not initiated until the currently determined state parameters exceed a specified limit value. For example, a correction proposal can be made only from a temperature difference of 5 degrees Celsius or from a weight difference of 50 grams. The correction suggestion may, for example, include the instruction to increase the temperature of the heating device of the food processor by a certain amount, so that the temperature of the food to be prepared on the desired value can be raised. If the current weight of the preparation material exceeds the reference weight, the correction proposal may, for example, include a prolonged heating period. It is proposed that the reference parameters are stored in the central data memory of the data communication network. In this respect, the central data store has a database with a plurality of reference parameters for different state parameters and / or operating parameters, which are recommended for preparing a recipe. Of course, such additional parameters or operating parameters are stored not only in relation to a single recipe but rather for a multiplicity of different recipes. By storing in the central data memory of the data communication network, a plurality of members of the data communication network can access the reference parameters particularly easily and make a comparison.

Furthermore, it is provided that the reference parameters are status parameters and / or operating parameters used by a member of the data communication network during a preparation. These reference parameters can be advantageously transmitted automatically from a kitchen machine of the member to the central data store in order to make these available to other members. The reference parameters may be parameters automatically detected by the sensors of the food processor or, alternatively, parameters manually stored by the member in the central data store. In particular, the reference parameters may already contain corrections which the member has recognized as beneficial in the course of the preparation of the corresponding recipe for the success of the preparation. In this respect, for example, the operating parameter "temperature" of a heating device of the food processor may be increased or the operating parameter In this respect, the central data memory of the data communication network may contain a multiplicity of different reference parameters for the same recipe, which as a whole provide, as an intersection, highly qualified practical support for the user in the preparation of the preparation material It is also possible, for example, for the user of the food processor not to use all the stored reference parameters for comparison with his current state parameters or operating parameters, but rather only those of selected members, for example, the selection may be based on the fact that the corresponding members have a For example, the reference parameters deposited by a member may provide a particularly high speed of the agitator to provide a finer consistency of the ingredients preparation to achieve good. Other users, for example, appreciate a coarser consistency, so they use a lower speed of the agitator.

It is proposed that the prepared correction proposal be transmitted directly from a data communication device of the member. In this respect, it is possible that the correction proposal is not created by the central server of the data communication network, but rather by a computer of the member. For this purpose, the member can copy or download the operating parameters and / or status parameters transmitted by another member and submit them to their own analysis. Subsequently, the member can create a personal correction proposal and submit it directly to a particular member without, for example, other members can access this correction proposal. Overall, the user of the food processor can thus receive individual, highly qualified and quick support in the preparation of a preparation material. The correction proposal can contain a wide variety of data. These include, for example, video data, audio data and / or text data. A video file can represent a specific preparation step clearly. For example, if the correction proposal consists of adding a certain amount of water to the preparation until it has reached a certain consistency or color, the addition and also the expected result can be recorded in the video in order to illustrate to the user the desired result. Alternatively or additionally, it is also possible that the correction suggestion not only contains a correction in the literal sense, but also informative video data or audio data with suggestions for accompanying wines or the like. In addition, music from the region of the recipe can be provided or similar.

Furthermore, it is proposed that the correction proposal is transmitted to the food processor and / or an external data communication device. The correction proposal can thus be transmitted either directly to the preparing food processor or additionally or alternatively to an external data communication device of the user, for example. A PC, mobile phone, tablet or similar.

The correction proposal can be displayed on a display of the food processor and / or the external data communication device.

This makes it possible that the user of the food processor can explicitly check the correction proposal or even change. Furthermore, it is possible that the user by means of the data communication device direct communication with another member of the data communication network, which provides a personal correction proposal or experience to prepare the corresponding recipe available has. The direct or via the central data memory of the data communication network indirect communication between different members of the data communication network is thus enabled and encouraged.

Advantageously, the correction proposal may contain control data, which are then used by the food processor for the preparation of the preparation material. If the user of the food processor wishes so, the control data can be used directly automatically for the further preparation of the preparation good. As a result, there are no time delays due to an examination of the correction proposal by the user. Rather, the correction is done without the user's intervention, so that the procedure is particularly simple and straightforward. Of course, it is also possible that the user first checks the correction proposal and then releases it before the control data control the food processor according to the correction proposal.

Furthermore, it can be provided that a time-recurring deviation of a state parameter of a preparation prepared in the food processor and / or a time-recurring deviation of an operating parameter of the food processor is saved and in future preparations of the same and / or another recipe in the form of a deviation from one recipe-appropriate operating parameters of the food processor is taken into account. For example, a time-recurring deviation of a state parameter of the preparation material may consist in the fact that the preparation always always (and in particular unintentionally) has a more fluid consistency than a preparation material according to the reference parameter. In this case, the evaluation device of the food processor or also an evaluation device assigned to the central data memory recognizes that this accessory Stand parameter often shows a deviation and draws appropriate conclusions. The deviation may, for example, result from the fact that the user uses foods which have a different consistency than an average food of this type. In particular, these foods may be tomatoes, eggs, quark or more, which often have a greatly varying size or a widely varying liquid content exhibit. In these cases, the operating parameters or possibly also the state parameters can be adjusted from the outset so that they meet the requirements and the foodstuffs used. For example, the recipe can be modified so that the user gets an indication that he should use only two tomatoes instead of three tomatoes in order to come very close to the desired preparation result. Likewise, certain operating parameters of the food processor can be adapted to the respective food, for example. In principle, a longer preparation duration can be provided in order to achieve the desired result. For example, it is also possible to provide a fundamentally higher speed of the agitator if it is known that the user generally uses honey or agave syrup instead of the usual table sugar. used. It is further proposed that information about additionally available for a preparation kitchen appliances is transmitted to the central data storage. These additionally available kitchen appliances are kitchen appliances of the user, which are available near the food processor. These kitchen appliances can, for example, additional heating appliances, blenders, oven, microwave or similar. be. In this sense, a correction suggestion may also contain the instruction to prepare a particular ingredient or at least a portion of the preparation material in the other kitchen appliance in order to obtain a specific preparation result. Advantageously, it can be provided that the kitchen appliances are automatically detected and identified by means of a code scanner or an image recognition device. The code scanner or the image recognition device can be a camera of a data communication device of the user, such as a mobile phone, which receives an image of the available kitchen appliances and transmits them to the central data memory of the data communication network for evaluation. It may then be searched in the data store for correction suggestions which provide for the use of one or more of these additional kitchen appliances.

In the following the invention will be explained in more detail with reference to an embodiment.

Figure 1 shows the kitchen of a user with a plurality of kitchen appliances 6 and a food processor 1. The food processor 1 is arranged in the illustrated embodiment on a countertop. The food processor 1 is designed as a fully automatic cooking-mixing device. This has a vessel 3, which are associated with a heater and an agitator. Furthermore, the food processor 1 has a display 8, on which the user information can be displayed and via which the user can transmit corresponding messages to the food processor 1. The kitchen further comprises kitchen appliances 6, such as here, for example, an oven and an additional hot plate, which can serve in addition to the food processor 1 the preparation of a preparation material 2.

The food processor 1 is integrated in a data communication network 5, to which other members, in particular other kitchen machines 1, can access. The data communication network 5 has a central data memory 4, in which recipes and reference parameters stored on specific recipes. The data communication network 5 is also a data communication device 7, here a laptop, the user connected. This data communication device 7 has in the usual way a display 8, on which the user information can be displayed.

The invention now works so that the user of the food processor 1 selects a recipe by which he wants to prepare a preparation material 2. The user can have previously extracted the recipe from the central data memory 4 of the data communication network 5. The data of the recipe, in particular operating parameters for the food processor 1 such as temperature settings of the heater and speed settings for the agitator are stored in a local data memory of the food processor 1. In the exemplary embodiment shown, the user has selected a recipe with which a stew can be prepared. The preparation material 2 includes, for example, tomatoes, potatoes, and the like. In the usual way, the user fills the preparation material 2 in the vessel 3 of the food processor 1 and then starts the operation of the food processor 1, which includes a heating of the preparation material 2 with simultaneous mixing by means of the agitator. In this case, the food processor 1 uses the operating parameters of the food processor 1 specified according to the recipe, for example a specific heating temperature of the heating device.

During the preparation of the preparation material 2 sensors associated with the kitchen appliance 1 measure the current state parameters of the preparation material 2, here for example the temperature of the preparation material 2. The temperature sensor currently measures, for example, a temperature of the preparation material 2 of 40 degrees Celsius. This measured condition parameter is sent with information about the recipe used and the current preparation progress to the central data memory 4 of the data communication network 5 transmitted. Other members of the data communication network 5 also access this central data memory 4 and deposit there the status parameters measured during preparation of the same recipe. All state parameters determined with regard to the same preparation progress form a database with a plurality of reference parameters in the central data memory 4.

The state parameter currently stored by the user of the food processor 1 is now compared with the reference parameters. For example, an average of all reference parameters can be used for comparison. The reference parameter, which has led to an optimal preparation result for other members of the data communication network 5, is on average, for example, a temperature of 80 degrees Celsius, which deviates from the currently measured state parameter (40 degrees Celsius). The reference parameters thus include a correction, which the other members of the data communication network have deposited in the central data memory 4, to give other members an indication of a necessary deviation from the recipe.

In the exemplary embodiment shown, the correction proposal is displayed to the user on the display 8 of his data communication device 7. For example, this may in concrete terms be the indication "Attention, raise the temperature to 80 degrees Celsius." Furthermore, the user may, for example, receive personal information from members of the data communication network 5. The possibility may also be provided by means of the data communication device 7 Establish communication link with another member of the data communication network 5 to get even more individual and direct assistance. It can now be provided according to a procedure that the user has to confirm the change of the operating parameter "temperature of the heater" to 80 degrees Celsius by means of the data communication device 7. The operating parameter of the food processor 1 only after confirmation by the user for the preparation According to an alternative procedure, it may be provided that the operating parameter to be changed is displayed to the user only informatively on the display 8 of the data communication device 7 (or also on the display 8 of the food processor 1 and then taken over fully automatically by the food processor 1) to control the heater to increase the temperature.

It can also be provided that a correction proposal is only submitted if the current state parameter, i. the current temperature, has a certain deviation from the reference parameter. For example, a temperature deviation of 5 degrees Celsius can not change the operating parameter of the food processor 1, i. the current setting of the heater result, while a deviation of 10 degrees Celsius leads to a change in the operating parameter. In the second case, the correction proposal prepared by the central data memory 4 of the data communication network 5 can contain control data which are suitable for controlling the food processor 1 in such a way that the desired preparation result is achieved.

In the case of a repeated preparation of the same recipe, recurring deviations in the consistency of the preparation material 2 may occur, for example a too liquid end result of the preparation material 2. In this case, by comparing with corresponding reference parameters, the correction be developed that the user of the food processor 1 should advantageously use only a smaller amount of a particular food, as this is above average hydrous and thus leads to a liquid preparation 2. The finding of this recurrent deviation can also be available for correction proposal of future preparations of the same recipe. For example. the user can be proposed from the outset a different amount of food, for example. Instead of three tomatoes only two. In addition, the other kitchen appliances 9, ie the oven or the additional hot plate can be integrated into the preparation of the preparation material 2. In particular, it is possible that correction proposals, which can be called off from the central data memory 4 of the data communication network 5 or directly by members of the data communication network 5, recommend an attendant warming of at least portions of the preparation material 2 in these kitchen appliances 9.

The aforementioned embodiment explains only a single possible process control of the inventive method for operating the electric motor driven food processor 1. It goes without saying that a variety of other variants is available, which different recipes, state parameters, operating parameters, other kitchen appliances 9, etc. can provide. In this respect, the embodiment shown is in no way limiting to the invention. LIST OF REFERENCE NUMBERS
